  • Outcomes of complicated congenital heart diseases following multiple re-sternotomy operations: A single-center experience

    ObjectiveTo analyze the outcomes of complicated congenital heart diseases (CCHD) patients accepting multiple (>2) re-sternotomy operations.MethodsWe retrospectively analyzed the clinical data of 146 patients undergoing multiple cardiac re-sternotomy operations between 2015 and 2019 in our center. There were 95 males and 51 females with an age of 4.3 (3.1-6.8) years and a weight of 15.3 (13.4-19.0) kg at last operation.ResultsThe top three cardiac malformations were pulmonary atresia (n=51, 34.9%), double outflow of right ventricle (n=36, 24.7%) and functional single ventricle (n=36, 24.7%). A total of 457 sternotomy procedures were performed, with 129 (88.3%) patients undergoing three times of operations and 17 (11.7%) patients undergoing more than three times. Fifty-two (35.6%) patients received bi-ventricular repair, 63 (43.1%) patients received Fontan-type procedures, and 31 (21.2%) patients underwent palliative procedures. Ten (6.8%) patients experienced major accidents during sternotomy, including 7 (4.8%) patients of urgent femoral artery and venous bypass. Eleven (7.5%) patients died with 10 (6.8%) deaths before discharge. The follow-up time was 20.0 (5.8-40.1) months, and 1 patient died during the follow-up. The number of operations was an independent risk factor for the death after operation.ConclusionSeries operations of Fontan in functional single ventricle, repeated stenosis of pulmonary artery or conduit of right ventricular outflow tract post bi-ventricular repair are the major causes for the reoperation. Multiple operations are a huge challenge for CCHD treatment, which should be avoided.

  • Mechanical valve replacement in complete atrioventricular septal defect—the decision making between common atrioventricular valvuloplasty and valve replacement in Fontan circulation

    A 12-year-old girl with double outlet of right ventricle, complete atrioventricular septal defect, pulmonary valve stenosis, single atrium, inferior vena cava-hemiazygos vein drainage and left isomerism, who had undergone surgical left superior vena cava-pulmonary artery connection was referred to our hospital. Echocardiography revealed thickening, crimping and malalignment of common atrioventricular valve, moderate-to-severe regurgitation mainly from the left side and the main pulmonary artery was poorly developed. We preserved the autologous valve and used the 31# mechanical mitral valve which was sutured to mitral annulus. After the main pulmonary artery was transected, proximal end was sutured and a 20# Gore-tex artificial vessel was anastomosed to the distal end of the main pulmonary artery. We excised hepatic vein from the right atrium which was then anastomosed to another artificial vessel. Postoperative oxygen saturation was 95%-100%. Echocardiography and CT showed that the function of mechanical valve and heart was good before discharge. Common atrioventricular valvuloplasty is the preferred choice of the management of impaired valve. However, when dysfunction of valve is too severe and valvuloplasty is more likely to fail, the risk of barely performing a valvuloplasty will increase dramatically. On this condition, the mechanical valve replacement should be performed.

  • Surgical management of total cavopulmonary connection procedure in functional single ventricle with separate hepatic venous drainage

    ObjectiveTo investigate the management of hepatic vein (HV) in patients with functional single ventricle (FSV) and separate hepatic venous drainage (SHVD) undergoing total cavopulmonary connection (TCPC) and evaluate this kind of surgery.MethodsThe clinical data of 32 consecutive patients with SHVD who underwent modified TCPC operation from August 2005 to January 2017 in our center were retrospectively analyzed. There were 25 males and 7 females with an average age of 2-19 (8.0±5.0) years and body weight of 11-66 (25.4±15.8) kg.ResultsThere were 20 patients with heterotaxy syndrome and 12 patients with other types of FSV. SHVD was diagnosed preoperatively in 27 patients, among whom 20 patients were connected by intra-extracardiac Gore-Tex conduit, and the other 7 patients were connected by extracardiac Gore-Tex conduit. Because of the missed diagnosis of SHVD, the other 5 patients showed severe decrease of blood oxygen saturation in the early postoperative period and underwent re-operation soon. The postoperative blood oxygen saturation was 92.0% (90.0%, 96.0%), central venous pressure was 10-23 (15.5±3.5) mm Hg, mechanical ventilation assisted time was 16.0 (7.5, 24.0) h, and ICU stay time was 3.0 (2.0, 5.5) d. There were 3 early and 1 late deaths.ConclusionIntra-extracardiac conduit is an effective and feasible modified TCPC operation for patients with FSV and SHVD, while the surgical details need to be formulated in combination with individual anatomical structure. Preoperative missed diagnosis of SHVD must be avoided. Otherwise, after TCPC, a large amount of stealing blood from HV with low circulation pressure into atrium would lead to unacceptable hypoxemia.

  • Outcomes of total cavopulmonary connection in the treatment of functional single ventricle with heterotaxy syndrome: A propensity score matching study

    Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). MethodsA retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). ConclusionCompared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.
